MRMS211H Equivalent & Substitute Parts

Part Overview

The MRMS211H is a magnetoresistive unipolar switch sensor manufactured by Murata Electronics, designed for digital switching applications with push-pull output configuration. This component operates across a supply voltage range of 1.6V to 4.6V with a maximum supply current of 12µA and features temperature compensation for stable operation across -40°C to 85°C. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MRMS211H is determined by the following critical parameters:

• Voltage Supply Range: 1.6V ~ 4.6V (must be compatible)
• Operating Temperature Range: -40°C ~ 85°C (must be compatible)
• Mounting Type: Surface Mount (must match)
• Package / Case: TO-236-3, SC-59, SOT-23-3 (must match)
• Technology: Magnetoresistive (must match)
• Supply Current: 12µA maximum (must not exceed)

The MRMS201A-001 qualifies as a substitute based on matching voltage supply range, operating temperature range, mounting type, package configuration, and magnetoresistive technology. While the MRMS201A-001 operates as a latch function (versus the unipolar switch function of the MRMS211H) and features dual polarization capability (North Pole and South Pole), it maintains electrical compatibility within the specified parameters and shares the same base product number (MRMS2) and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The MRMS201A-001 is available as an active product with current manufacturing support from Murata Electronics, whereas the MRMS211H is obsolete. Both components share identical electrical specifications for supply voltage (1.6V ~ 4.6V), maximum supply current (12µA), and operating temperature range (-40°C ~ 85°C). Both are packaged in TO-236-3 / SC-59 / SOT-23-3 surface mount configurations and utilize magnetoresistive sensing technology.

The MRMS201A-001 carries ROHS3 compliance certification, providing regulatory advantage for new designs. Both components maintain REACH Unaffected status and EAR99 export classification. The MRMS201A-001 is supplied in Tape & Reel packaging with significantly higher inventory availability (16,462 pieces versus 6,090 pieces for the MRMS211H).

Frequently Asked Questions (FAQ)

Q: Can the MRMS201A-001 directly replace the MRMS211H in existing designs?

A: The MRMS201A-001 matches all critical electrical parameters: supply voltage range (1.6V ~ 4.6V), maximum supply current (12µA), operating temperature range (-40°C ~ 85°C), and physical package (TO-236-3 / SC-59 / SOT-23-3). Both utilize magnetoresistive technology. The primary functional difference is that the MRMS211H operates as a unipolar switch with push-pull output, while the MRMS201A-001 operates as a latch with digital output. Application-specific requirements must be evaluated to determine functional compatibility.

Q: What are the key differences in sensing characteristics?

A: The MRMS211H features a sensing range of 1.6mT trip and 0.6mT release with South Pole polarization. The MRMS201A-001 features a sensing range of 2.5mT trip and 0.5mT release with dual polarization capability (North Pole and South Pole). These differences affect magnetic field detection thresholds and may impact system performance depending on magnet placement and field strength in the application.

Q: Are there packaging differences between these components?

A: Both components use identical package configurations (TO-236-3, SC-59, SOT-23-3). The MRMS211H is supplied in standard packaging, while the MRMS201A-001 is supplied in Tape & Reel format, which is standard for high-volume manufacturing and automated assembly processes.

Q: What compliance certifications apply to the MRMS201A-001?

A: The MRMS201A-001 is ROHS3 compliant and maintains REACH Unaffected status. Both the MRMS211H and MRMS201A-001 carry EAR99 export classification and share the same HTSUS code (8536.41.0030).
